This is very close to being a bit pricey for a DAC in my opinion, but it is a quite capable one and I imagine if one were to purchase this I would expect it to be the last DAC one would need to get at it’s just under 800 clams, it better be. With its AES and XLR outputs and decoding capability of PCM 384K & DSD256, the NuPrime DAC-9 is a reference-class DAC designed for studio professionals. With four digital and one analog stereo inputs, the DAC-9 is a full-featured DAC and preamp ideally suited for high-end systems.http://www.nuprimeaudio.com/index.php/products/dacs-and-headphone-amps/home-audio-dacs/dac-9.html
Several notable features:
NuPrime SRC IC chip provides FPGA processing where Input signals are up-sampled to mega hertz before down converted to the targeted sampling rate with ultra-low jitter and distortion.
AKM Newest Generation: High Sound Quality Premium 32-bit Stereo DAC (AK4490 EQ). State-of-the-art DAC with warmer sonic characteristics, supporting USB PCM 384 and DSD256.
A proprietary NuPrime implementation that is also capable of decoding DoP formats via coaxial and optical inputs (to support NuPrime Omnia portable device that are able to output DoP stream in addition to S/PDIF).
NuPrime vibration-free isolation feet (patent pending*)
Extension port for Bluetooth dongle and WiFi audio streaming (optional)
Full microprocessor control with memory retention
Five digital inputs and one stereo input for complete system flexibility
Supports DSD native playback by ASIO2.1 and DoP method. DSD is decoded natively with the same sample rate as the input source.
Ultra-low-noise JFETs in the input stage for the lowest possible noise floor
Volume adjustment in 99 precise 0.5dB increments
Advanced, FPGA implemented thin-film switched-resistor ladder network for controlling volume, with a single resistor in the signal path at any volume setting
Individually adjustable volume on each input for precise level matching of sources. If DAC-9 is connected to another preamp or home theater AVP, set the volume @ 94, which is 0dB.
Exclusive driver software for Windows
Standard driver software for Mac
Asynchronous transfer mode
Very low power consumption on Standby Mode
